Abstract: An epihalohydrin is condensed in solution with an alkylenepolyamine having at least one tertiary amino group in the molar ratio of from 0.5 to 1.75:1, and the condensate quaternized and then neutralized to prevent cross-linking. A mixture of an alkylene-polyamine and a polyalkylene-polyamine having only primary and secondary amino groups may also be used.  The condensate is prepared by direct reaction, preferably at 15-40 DEG  C.  Quaternization is carried out in the presence of an alkali. Suitable alkylenepolyamines are N,N - dimethylpropylenediame, N,N - diethylpropylenediame, N-morpholinopropylamine, dimethylaminoethylamine, diethylaminoethylamine, N,N - dimethyl - N1 - methylpropylenediamine, N,N-dimethyl - N1 - methylethylenediamine, N,N-diethyl - N1 - ethylethylenediamine, and dimethylaminopropylamine. Suitable polyalkylenepolyamines are lower polyethylenepolyamines and polypropylenepolyamines.  Suitable quaternizing agents are alkyl halides, dialkyl sulphates, epihalohydrins and alkyl esters of aryl sulphonates.  In the examples, dimethylaminopropylamine is mixed with water, and epichlorohydrin added.  In example (2) the mixture was then made alkaline and methyl chloride added.  Uses.-Impregnating and coating agents, liquid ion exhangers, coagulant aids, acidcorrosion inhibitors, metal complexing agents and anti-static agents.ALSO:Textiles are treated with a solution, preferably aqueous of the quaternized and neutralized condensate of an epihalohydrin and an alkylene polyamine by calendering, brushing, dipping or spraying the textile with the solution, and drying.  The alkylene polyamine has at least one tertiary amino group and the condensate is prepared using a molar ratio of epihalohydrin to polyamine of 0.5 to 1.75:1. A mixture of an alkylene polyamine and a polyalkylene polyamine having only primary and secondary amino groups may be used in preparing the condensate.  The solutions serve as anti-static agents. Textiles mentioned include cellulose, cellulose esters, rayons, nylons, wool, silk and vinyl resins.  Quaternization is carried out in the presence of an alkali, followed by neutralization to prevent cross-linking, and with the following quarternizing agents:-alkyl halides, dialkyl sulphates, epihalo-hydrins, and alkyl esters of aryl sulphonates. Suitable alkylene polyamines are N,N-dimethyl propylenediame, N,N-dialkyl-propylene diame, N-morpholisopropylamine, dimethylamino ethylamine, diethylamino-ethylamine, N,N-dimethyl-N\sv-methyl-propylene diamine, N,N-dimethyl-N\sv-methylethylene diamine, N,N-diethyl-N\sv-ethyl ethylene diamine and dimethylaminopropylamine.ALSO:Coating and impregnating agents may be applied to plastics and textiles and consist of a solution preferably aqueous of the quaternized condensate of an epihalohydrin and an alkylene polyamine, having at least one tertiary amino group, in the ratio of .5 to 1.75:1.  The solutions serve as anti-static agents. Textiles mentioned include cellulose, cellulose esters, rayons, nylons, wool, silk and vinyl resins.  The plastics include polyethylenes, polypropylenes, polystyrenes, and polyvinyl chlorides.  The treatment of textiles is described, in which the aqueous solution, having a pH of about 6 is applied by calendering, brushing, dipping or spraying on to a vinyl resin, and the material dried.  A mixture of an alkylene polyamine and a polyalkylene polyamine having only primary and secondary amino groups may also be used.  Quaternization may be carried out in the presence of an alkali, followed by neutralisation to prevent cross-linking, and with the following quaternizing agents:-alkyl halides, dialkyl sulphates, epihalohydrins, and alkyl esters of aryl sulphonates.  Suitable alkylene polyamines are N,N-dimethylamine propylene diame, N,N-dimethylamino propylene diame, N-morpholino-propylamine, dimethylamino ethylamine, diethylamino ethylamine, N,N-dimethyl-N1-methyl propylene diamine, N,N-dimethyl-N1-methyl ethylene diamine, N,N-diethyl-N1-ethyl ethylene diamine and dimethylamino propyl-amine.
